manufacture and shipped to the place of use where they are nailed to the roof deck, flat'- Vheaded nails being frequently employed for this purpose. These sheets' of roofing are laid with their edges over-lapping, the nails passing through the overlapped portions,

and it is desirable that the amount of overlap of all Sheets should be uniform as well as the spacing of the nails, and that the nails along each lap should'be driven in line each with the others. My o invention provides a simple but effective device for accomplishing these results and generally facili-V tating the laying of the roofing.l `The best form of apparatus embodying my invention at present known to me is illustrated in the accompanying sheet ofdrawing in which-f- Fig. 1 is a plan viewof a portion ofa roof, parts being broken away, showing the gauge in one of the positions it would occupy in l is the roof deck and 2, 3,4 and rjrepre sent sheets of prepared roofing nailed, or' to be nailed thereto. These' sheets are laidV on an inclined roof deck oi surface with their longer dimensions horizontal, so that the longer lap between each two adjacent sheets is called'the horizontal lap and the shorter lap is called the vertical lap. According to the prevailing customV in vr'the art,'the width of the horizontal lap is 2 inches and that of the vertical lap 3 inches, and the nails are set with their centers three-quarters of an inch backfrom the outer edge of each lap and 2 inches apart,all as indicated by way Specification of Letters'Pa'tent. auf; 31,'

6 is the gauge which is made of a strip ofl wood or other stiff material, usually-36, inches long and 2 inches wide, having. one edge, as 9,

beveled. In one edge ofthe strip, preferably c' the one not beveled, is cut a series of trans verse slots v7, 7 two inches between center lines, each wide enough to receive a naily (usually. three-sixteenths of an inch in diam-V eter), and deep enough to allow -such ay nail, when placed at the bottom of aslot, .to c l have its center/distant three-quarters of an inch from the line of the slotted edge of the Y gauge. f8, 8 are vhalf slots formed at'either end of the gauge. The unslotted edge of the gauge'may be given the usual graduatioiis showing inches and fractions thereof, andV oneof these, at the 3-inch point from one end, may be prolonged as shown at`13, or otherwise distinguished. f i

In uselthe gauge may be laid alongv the edge of any one sheet of roofing, already in position, to indicate the proper width of yhorizontal lap, and the adjacent sheet tering "with lthey inner edge of the gauge. This will llocate the Aloose sheet in the proper Y position to give the desiredv 2-inch horizon- The loose sheet being properly located, the

gauge is placed along one edge, such as the edge of the horizontal lap 1l, and with the half slot 8 at one end engaging the last lnail* in the next sheet, as shown in Fig. 1'.,v

saidl lastV nail having been driven only vhalf laid over it with its overlapping edge regis- The nails l0 are .then driven throughV thev slotsl 7, 7, half way home, as

indicated in 2. The gauge` is then f. swung upon the end nail asa pivot tosimilarly space the nails forthe adj acent'vertical lap. .Then the gaugefis removed and all the `nails, are driven home. The'foregoing opera-l 1 ltions are vrepeateduntil the roof isrcoveredand Vall sheets nailed in position. v

I preferably make theV gauge of a strip a quarter inch thick' and bevel one-half of `one face down-tov a thickness of one-eighth` inchat theedge l9, as indicated in Fig. t.Y

Having described my invention I claim: 1.As a vnewl articlev of lmanufacture a gauge, for laying prepared roong said gauge comprising a stripv .of stiff material.

having a series Aof slots in one'edge, spaced apart by thel distances at Whchithe nails to 3. A stroture'suoh as descbed in claim 10 be used in holding the roofing in position are 1-Whioh has a Width equal to the Width of spaced apartand of a depthnequalto thedisthe overlap at the longer edges of the sheets tance which such nails are to loe setback of roong, and has one edgebeveled.l

from the edge of each sheet of the roono.

2. A structure such as set forth in olan l .Y v JAMES VILSON' also having each end out away to conform Y Vtnesses: to the outline of one-half of one of the slots Y JAooB M. BERDAN, such as are therein described. l CHARLES J. BEQKWITH--
